Answer:
2.0/4.0
Step-by-step explanation:
Answer:
Option B
Step-by-step explanation:
By the midsegment theorem,
"Midsegment of a trapezoid is half the sum of the parallel bases"
By this theorem,
y + 6 =
2(y + 6) = (3y + y) +(-7 + 3)
2y + 12 = 4y - 4
2y - 4y = -12 - 4
-2y = -16
2y = 16
y = 8
Therefore, length of the midsegment = y + 6
= 8 + 6
= 14
Option B will be the answer.
Since we are given that y is directly proportional to x and that when y = 11, x equals 6, we can set up a proportion. Before doing that however, we need to note that the question is asking for the value of y when x = 9. Here is the equation:
Now, just cross multiply and solve for y to get a value of 16.5. Therefore, the value of y when x = 9 is
16.5. Hope this helped and have a phenomenal day!

Answer: x = 72
Step-by-step explanation: Although the problem is saying "X over 8", this really signifies that the <em>x</em> is being divided by 8 which is what a fraction is, numerator divided by a denominator.
Let's first undo what has been done. Since our variable is being divided by 8, we'll undo that by multiplying by 8 on both sides. It's important to remember, whatever you do on one side,
you <u><em>must</em></u> do to the other side.
If you look now, the 8 in the numerator and the 8 in the denominator will divide out and it will leave us with our variable which is <em>x</em>. Working on the other side now, 9 x 8 is equal to 72 so <em>x = 72</em> is our answer.
We can check our answer by plugging a 72 back into the original equation. So we have 72/8 = 9 which is a true statement
so our answer is correct.
